The Moving Picture Experts Group (MPEG) is a working group in charge of the development of standards for coded representation of digital audio and video.

MPEG audio and video clips are ubiquitous but using Perl to programmatically collect information about these bitstreams has to date been a kludge at best.

This module uses the libmpeg3 library to parse and extract information from the bitstraems. It supports the following types of files:

MPEG-1 Layer II Audio
MPEG-1 Layer III Audio
MPEG-2 Layer III Audio
MPEG-1 program streams
MPEG-2 program streams
MPEG-2 transport streams
AC3 Audio
MPEG-2 Video
MPEG-1 Video
IFO files
VOB files

MPEG::MP3Play is a Perl extension for playing back MPEG music.

SYNOPSIS

use MPEG::MP3Play;
my $mp3 = new MPEG::MP3Play;

$mp3->open ("test.mp3");
$mp3->play;
$mp3->message_handler;

This Perl module enables you to playback MPEG music.

This README and the documention cover version 0.15 of the MPEG::MP3Play module.

MPEG Streamclip converts QuickTime movies, MPEG-1/2/4 files and transport streams into several formats; for MPEG-2 playback and export, the QuickTime MPEG-2 Playback Component is required.

MPEG Streamclip can play and convert selectable parts of QuickTime movies, MPEG files and transport streams with MPEG/AC3/PCM audio into DV streams or QuickTime, AVI, MPEG-4 movies using any video codec, with optional 2D-FIR professional scaling, motion-adaptive deinterlacing, and other pro options; all in YUV, with audio in perfect sync.

It also performs fast conversions to muxed MPEG files and demuxed M2V, AIFF, M1A, AC3 files, for direct burning with DVD Studio Pro and Toast 6 or 7.

eXstream MPEG is a small utility which is able to read most types of MPEG video streams (including VOBs) and to convert them to AVI.

You can use MPEG Streamclip to: open and play most movie formats including MPEG files or transport streams; edit them with Cut, Copy, Paste, and Trim; set In/Out points and convert them into muxed or demuxed files, or export them to QuickTime, AVI, DV and MPEG-4 files with more than professional quality, so you can easily import them in a DVD authoring tool, and use them with many other applications or devices.

MPEG Streamclip is a software that allows you edit movie files.

Here are some key features of "MPEG Streamclip":

· MPEG Streamclip lets you play and edit QuickTime, DV, AVI, MPEG-4, MPEG-1; MPEG-2 or VOB files or transport streams with MPEG, PCM, or AC3 audio. MPEG Streamclip can export all these formats to QuickTime, DV/DV50, AVI/DivX and MPEG-4 with high quality encoding and even uncompressed or HD video.
· Video conversion is performed in the YUV color space; you can choose to scale video to any frame size using a professional 2D-FIR scaler (better than bicubic) but you can also leave it unscaled. Other optional video processing features include a powerful motion-adaptive deinterlacer, a field dominance converter, a chroma reinterlacer and an option to perform interlaced scaling instead of progressive scaling. Audio can be converted to uncompressed or to IMA, AAC, MP2 or AMR using the high-quality MP1/MP2/AC3/PCM built-in decoders of MPEG Streamclip; it is also kept in perfect sync with video using a timekeeping system.
· MPEG Streamclip can save edited movies as MOV files, and (when possible) as AVI or MP4 files. Edited MPEG-1 or MPEG-2 files are saved as MPEG or TS files.
· MPEG Streamclip can also convert MPEG-2 transport streams into muxed MPEG-2 files, for immediate burning at full quality with most DVD authoring applications; it can also demux MPEG-1 and MPEG-2 files and transport streams with MPEG, AC3, PCM audio to M2V and AIFF (or M1A or AC3) files, for immediate burning at full quality with DVD authoring applications. A special demuxing option is available for use in QuickTime Pro: this application does not work well with M2V files, but MPEG Streamclip can write a special "unscaled" M2V file that preserves full video quality.
· MPEG Streamclip can handle files and streams larger than 4 GB, split in any number of segments, or with multiple audio tracks, and can also optionally handle timecode breaks. It is compatible with MPEG-1 and MPEG-2 video, MPEG layer 1/2 (MP1/MP2) audio, AC3/A52 audio, and PCM audio.
· The player included in MPEG Streamclip lets you preview the files and transport streams before doing the conversion; it also lets you visually set the In and Out points for the conversion so you can convert just the part of the file you are interested in, and also cut commercials and other unwanted parts, or edit the stream and join two streams with Cut/Copy/Paste.

MPEG Streamclip is a converter, an encoder, a player and an editor.

Converter features:
- from MPEG, MPG, VOB, PS, M2P, MOD, VRO, DAT, TS, M2T, MMV, REC, VID, AVR to MPEG, TS, M2V, AIFF, M1A, AC3

Encoder features:
- from MOV, AVI, DV, MP4, MPEG, MPG, VOB, PS, M2P, MOD, VRO, DAT, TS, M2T, MMV, REC, VID, AVR, M2V to MOV, AVI, DV, MP4
- MP4 (MPEG-4) files are compatible with Apple iPod and with 3G cellphones
- supports any QuickTime-compatible video codec available for Windows, and many audio formats
- very high quality encoding, all in YUV color space, either unscaled or with 2D-FIR scaling (better than bicubic)
- motion-adaptive deinterlacing and chroma reinterlacing, with perfect audio/video sync

Player features:

- playback of muxed/demuxed MPEG/VOB files and transport streams with MPEG, AC3, PCM/AIFF audio
- playback of MPEG files larger than 4GB, or segmented in many files
- support for multiple audio tracks in transport streams and MPEG/VOB files

Editor features:
- cut/copy/paste of MPEG files and transport streams, at keyframe (GOP) level

MPEG2VCR is a tool created before MPEG Video Wizard, but loyal users still love it. It is a software video editor that performs all editing on MPEG data with frame accuracy.

It supports all MPEG-1 and MPEG-2 bit streams, including MPEG-2 Transport streams for HDTV. Its major features are list below.

Frame accurate editing: step forward and backward through your video, frame-by-frame, to find exactly the scene you want, or to cut out the ones you dont.

Fastest scrubbing of any MPEG-2 editor: Scroll through your entire movie as fast as your mouse can drag the slider. Quickly find the scenes you want to keep, or the ones you want to cut.

Fastest frame stepping of any MPEG-2 Editor. Move through your video frame-by-frame at the click of your mouse, or the press of a key. Makes it super easy to zero-in on exactly the desired frame to be edited.

No re-encoding when editing DVD-compliant MPEG-2 captures from the latest USB/DVD capture boxes. When using these sources to create a movie for DVD burning, you will not have to wait for many hours while your movie is re-encoded. Instead, your edited video will be written back to disk as fast as any disk-to-disk copy operation.

MPEG::ID3v2Tag is a Perl module that parses and creates ID3v2 Tags for MPEG audio files.

SYNOPSIS

use MPEG::ID3v2Tag ;
use IO::File ;

# create a tag
$tag = MPEG::ID3v2Tag->new() ;
$tag->add_frame("TIT2", "Happy Little Song") ; # one step
$frame = MPEG::ID3Frame::TALB->new("Happy little album") ;
$tag->add_frame($frame) ; # two steps
$tag->add_frame("WCOM", "http://www.mp3.com") ;
$tag->add_frame("APIC", -picture_type => 0, -file => "happy_little_song.gif");
.....
$tag->set_padding_size(256) ;
print OUTFILE $tag->as_string() ;

# read a tag from a file and dump out some data.
$fh = IO::File->new(" binmode $fh;
$tag = MPEG::ID3v2Tag->parse($fh) ;
foreach $frame ($tag->frames()) {
print $frame->frameid(), "n" ; # prints TALB, TIT2, WCOM, etc.
if ($frame->flag_read_only()) {
print " read onlyn" ;
}
if ($frame->fully_parsed() && $frame->frameid =~ /^T.../) {
print " frame text is ", $frame->text(), "n" ;
}
if ($frame->fully_parsed() && $frame->frameid =~ /^W.../) {
print " url is ", $frame->url(), "n" ;
}
}

MPEG::ID3v2Tag is a class capable of parsing and creating ID3v2 revision 3 tags. While not all frames are fully supported, its easy to add support for more.
The object doesnt (currently) support modification of .mp3 files; the caller has to handle the mechanics of prepending the tag to the file.

MPEG::MP3Info is a Perl module to manipulate / fetch info from MP3 audio files.

This is just a wrapper around MP3::Info now.

A wrapper module is included so scripts calling MPEG::MP3Info (the old name) will still work.

MPEG Parser is a utility that shows you the structure of a MPEG file.

MPEG Parser is the viewer of MPEG-files internal structure. It can view fields of structures of what the MPEG file consists.

MPEG Parser shows next data about MPEG file: Resolution, Frame rate, Size, Aspect ratio, Bitrate ... Utility allows to correct errors in MPEG - use menu item "Save corrected..." for this. You can also save internal structure in the text file via menu item "Save MPEG information...".

Mpeg Splitter is a tool for splitting an MPEG(MPG) file into smaller MPEG files. You can preview the MPEG file, set the start time and the end time, split or cut any section of the MPEG file you want. Mpeg Splitter also splits equal parts either by size or by time. Mpeg Splitter is especially useful for splitting mpeg1 files from Digital Video or Digital Camera. You can download the trial version of Mpeg Splitter freely.

MPEG Encoder is an encoding tool that can encodes video files from AVI, MPEG, WMV format to MPEG format (supports MPEG-1 and MPEG-2).

The MPEG format features better video quality, higher compression, and gives users better vision feeling.

The MPEG-1 is used for Video CD (VCD) burning. And the MPEG-2 is used for Super Video CD (SVCD) and Video DVD burning.

Here are some key features of "MPEG Encoder":

· Encode to MPEG-1
· Encode to MPEG-2
· Input from MPEG
· Input from AVI
· Input from WMV
· Support templates
